Rotary cam alignment system

An improved system used for alignment of a vehicle suspension and axle includes a cam plate that is rotatable relative to one of two spaced plates of a hanger bracket about an axis of rotation extending through a center of the cam plate. An aperture in the cam plate is aligned with an elongated opening in the bracket plate and defines a cam surface. A bushing may be disposed in the aperture and ride on the cam surface. A fastener extends through the bushing, the elongated openings in the bracket plates, and the suspension control arm. Rotation of the cam plate and movement of the bushing and the fastener along the cam surface of the aperture displaces the fastener along the elongated openings of the bracket.
